Marketplace Fees Calculator
Calculate the total fees charged when selling on an online marketplace, combining the percentage-based referral fee with any fixed closing fee. Essential for sellers pricing products to protect their profit margins.
About this calculator
Online marketplaces like Amazon, eBay, and Etsy typically charge two types of fees: a referral fee (a percentage of the sale price) and a fixed closing fee per transaction. The total marketplace fee formula is: Total Fees = (Sale Price × Referral Fee%) + Closing Fee. For instance, if you sell an item for $50 with a 15% referral fee and a $1.80 closing fee, your total fee is (50 × 0.15) + 1.80 = $9.30. Understanding this combined fee structure is critical because even small percentage differences in referral fees can significantly impact margins on low-priced or high-volume products. Sellers use this calculation to set minimum viable prices and compare the true cost of selling across multiple platforms.
How to use
Suppose you list a product at a sale price of $75, the marketplace charges a 12% referral fee, and there is a $1.50 closing fee. Enter salePrice = $75, referralFee = 12, and closingFee = $1.50. The calculator computes: ($75 × 12 ÷ 100) + $1.50 = $9.00 + $1.50 = $10.50. Your total marketplace fees are $10.50, leaving $64.50 before accounting for product cost and shipping. Use this figure to verify that your pricing covers all costs and delivers your target profit margin.
Frequently asked questions
How do marketplace referral fees affect my product pricing strategy?
Referral fees directly reduce the revenue you receive per sale, so they must be built into your pricing from the start. If you set a price without accounting for a 15% referral fee, you are effectively giving away 15 cents of every dollar earned. A practical approach is to work backward: decide your target net revenue, add your costs, then add the referral fee on top to arrive at a minimum list price. Comparing referral fee rates across platforms can also reveal which marketplace is most cost-effective for your specific product category.
What is the difference between a referral fee and a closing fee on marketplaces?
A referral fee is variable — it scales with your sale price as a fixed percentage, typically ranging from 6% to 20% depending on the product category. A closing fee is a flat dollar amount charged per transaction regardless of the sale price, common on media and collectibles categories. On low-priced items, the closing fee can represent a disproportionately large share of total fees. Understanding both components is essential for accurately modeling your per-unit economics.
Which online marketplace has the lowest selling fees for small businesses?
Fee structures vary significantly by marketplace and product category, making a direct comparison difficult without knowing your specific niche. Amazon's referral fees range from 6% to 45% depending on category, while eBay charges around 13.25% for most categories plus a small final value fee on shipping. Etsy charges a 6.5% transaction fee plus listing fees. Smaller niche marketplaces sometimes offer lower fees but come with reduced traffic. Always calculate your all-in fee using this calculator for each platform before choosing where to sell.
